Hi everybody. I'd need to know how a FIR filtering works. From datasheet I read that:
- multiplier have 28x28 bits and I suppose 56bits output, right? Is the 56bits output also for FIR filtering?
- accumulator have 56bits but in full precision mode, for FIR filters is the same, since FIR filtering works in signle precision?
Knowing these infos I can decode the entity of round and roundoff error for FIR filtering having high taps.
I hope you can help me.
